On the first step a discretization method for solving differential equations of the PLL systems is presented. It is shown that there are a lot of zones of synchronous in discretized PLL and a technical realization of this device (in PLL with samples). A spectra... View full abstract»

    In this paper we discuss a new approach to create the acoustic atmospheric radar (sodar) which is based on noise sounding waveform. Such sounding waveform fits all formal requirements to UWB signals and has remarkable characteristics including extremely high range and speed resolution. It is important to remember that all these good properties exist only in the case when we have independent sample... View full abstract»
